在网络化迅速发展的今天,网络的传输内容早已不仅仅局限于简单的数字、声音、图像等,许多信息形式都在成为网络传输的对象。近两年来,国内众多IT厂商都在积极进行视频信号网络传输领域的探索。而由于现有网络的硬件条件的限制,图像的传输虽然已经实现,但真正理想的图像传输还很难达到。作为 With the rapid development of network, the transmission content of the network has long been not only limited to simple numbers, sounds, images, etc. Many forms of information have become the object of network transmission. In the past two years, many IT companies in China have been actively exploring the field of video signal network transmission. However, due to the limitation of the hardware conditions of existing networks, although the transmission of images has been achieved, the real ideal image transmission is still difficult to achieve.
